FIRE Number Calculator

How Much Do You Need to Retire Early?

Your FIRE number is the portfolio size you need so your investments can support your lifestyle indefinitely. The most common method is the 4% rule: divide your annual expenses by 0.04, or multiply by 25. At $48,000 per year in expenses, your FIRE number is $1.2 million.

Frequently asked questions about FIRE numbers

What is a FIRE number?
Your FIRE number is the total portfolio value you need so you can live off investment returns without working. It is calculated by dividing your expected annual expenses by your planned withdrawal rate. Using the 4% rule, your FIRE number is 25 times your annual spending.
How do I calculate my FIRE number?
Take your expected annual expenses in retirement and divide by your withdrawal rate. For example: $60,000 annual expenses ÷ 0.04 (4% rule) = $1,500,000 FIRE number. You can also multiply annual expenses by 25 to get the same result.
Is the 4% rule still valid?
The 4% rule is a commonly used planning starting point, based on historical research showing a 4% annual withdrawal from a diversified portfolio has historically lasted 30+ years. More conservative planners use 3% to 3.5%, particularly for early retirees with longer time horizons. The right rate depends on your risk tolerance, expected retirement length, and portfolio mix.
How does location affect my FIRE number?
Your FIRE number is directly tied to your annual spending. If you move to a lower cost-of-living city or a state with no income tax, your annual expenses in retirement may be lower — which means a smaller FIRE number and potentially years shaved off your timeline.
Do I need to include taxes in my FIRE number?
Yes, ideally. In retirement, withdrawals from taxable accounts and traditional 401(k) or IRA accounts are subject to income tax. Your effective tax rate in retirement depends on your withdrawal strategy, account mix, and state of residence. This calculator applies a state-specific tax model to help you plan more realistically.
What is the difference between FIRE, Lean FIRE, and Barista FIRE?
Traditional FIRE targets a portfolio that fully covers all living expenses. Lean FIRE uses a smaller number by targeting a frugal lifestyle, typically under $40,000 per year. Barista FIRE is a partial retirement strategy where you cover some expenses with part-time income so your portfolio needs to be smaller. Each approach has a different FIRE number.
